Nothing new in the world? Nothing left to discover? NASA would beg to differ. The discovery of an "enormous, off-the-charts" bloom of microscopic marine plants in the Arctic has floored scientists. And it confirms, if nothing else, that there are things on this planet not yet seen -- things that you "never, ever could have anticipated in a million years. " So says Paula Bontempi of NASA. An ocean biology and biogeochemistry program manager in Washington, Bontempi spoke with the Los Angeles Times on Friday morning about the discovery. Here's how it came about: Over the summers of 2010 and 2011, NASA's Icescape expedition was exploring the Arctic waters of the Beaufort and Chukchi seas off Alaska.

Ladies and gentlemen, the Voyager 1 spacecraft has left the solar system - or has it? Scientists are continuing to debate whether the lonesome craft has finally escaped the solar system after 35 years of travel or has simply entered a previously unknown region of solar influence. On Wednesday, a study published in Geophysical Research Letters , a journal of the American Geophysical Union, suggests that the Voyager spacecraft exited the heliosphere - that region of space dominated by solar winds and long considered to be the edge of the solar system - on Aug. 25, 2012.

Scientists have caught the first images of a boa constrictor consuming a 9-pound howler monkey, and they are gruesome. In the gallery above, you will see the boa constrictor ingesting the monkey head-first, bit by bit. The images accompany a study describing a play by play of the snake attack published in the journal Primates by Julio Cesar Bicca-Marques of Pontifical Catholic University of Rio Grande do Sul and his student ...

WASHINGTON -- The Smithsonian National Zoo announced Thursday that the giant panda cub born there two weeks ago is a girl, is very chatty and "has a fat little belly. " Scientists confirmed the sex of the cub, which was born to Mei Xiang (pronounced may-SHONG) on Aug. 23, according to a news release. DNA tests also showed that the zoo's panda Tian Tian (t-YEN t-YEN) is the father of the cub. Mei Xiang was artificially inseminated twice in late March, with sperm from Tian Tian and from a panda named Gao Gao at the San Diego Zoo, after unsuccessful natural breeding attempts with Tian Tian.

Screaming at your teenagers to discipline them can make their behavior worse - even if you otherwise have a warm family relationship, researchers say. The effects were comparable to those in studies that focused on physical punishments, the researchers said. “From that we can infer that these results will last the same way that the effects of physical discipline do,” the lead researcher, Ming-Te Wang, an assistant professor of psychology in education at the University of Pittsburgh, said in a statement.

A team of storm-chasing scientists sampling rarefied air has found a world of bacteria and fungi floating about 30,000 feet above Earth. The findings, detailed Monday in the Proceedings of the National Academy of Sciences, suggest that microbes have the potential to affect the weather. Scientists have long studied airborne bacteria, but they typically do so from the ground, often trekking to mountain peaks to examine microbes in fresh snow. Beyond that, they don't know much about the number and diversity of floating microbes, said study coauthor Athanasios Nenes, an atmospheric scientist at Georgia Tech.

The dark dust thrown up by human activity in the deserts of the Southwest hastens the melting of Rocky Mountain snow and ultimately reduces the amount of water flowing into the upper Colorado River by about 5%, scientists reported Monday. The lost water amounts to more than 250 billion gallons — enough to supply the Los Angeles region for 18 months, said study leader Thomas H. Painter, a snow hydrologist at the Jet Propulsion Laboratory in La Cañada Flintridge. "That's a lot of water," said Painter, whose study was published online by the Proceedings of the National Academy of Sciences.

AS they seek to document and demystify one of life's great thrills, scientists have run across some real head-scratchers. How, for example, can they explain the fact that some men and women who are paralyzed and numb below the waist are able to have orgasms? How to explain the "orgasmic auras" that can descend at the onset of epileptic seizures -- sensations so pleasurable they prompt some patients to refuse antiseizure medication? And how on Earth to explain the case of the amputee who felt his orgasms centered in that missing foot?

Is 2012 the end of the world? If you scan the Internet or believe the marketing campaign behind the movie "2012," scheduled for release in November, you might be forgiven for thinking so. Dozens of books and fake science websites are prophesying the arrival of doomsday that year, by means of a rogue planet colliding with the Earth or some other cataclysmic event. Normally, scientists regard Internet hysteria with nothing more than a raised eyebrow and a shake of the head. But a few scientists have become so concerned at the level of fear they are seeing that they decided not to remain on the sidelines this time.

According to the conventional wisdom that liberals accept climate change and conservatives don't, Kerry Emanuel is an oxymoron. Emanuel sees himself as a conservative. He believes marriage is between a man and a woman. He backs a strong military. He almost always votes Republican and admires Ronald Reagan. Emanuel is also a highly regarded professor of atmospheric science at MIT. And based on his work on hurricanes and the research of his peers, Emanuel has concluded that the scientific data show a powerful link between greenhouse gas emissions and climate change.
